Hello,

I try some examples of the realword Ocaml book but now I see this
output :

# let ratio x y = Float.of_int x / Float.of_int y ;;
Error: Unbound module Float
# open Core.std ;;
Error: Syntax error
# open Core.Std ;;
Error: Unbound module Core

How to solve this ?

Roelof

I strongly recommend using utop as toplevel. Then in utop enter

#require "core";;

Otherwise for a standard ocaml toplevel with findlib and core libraries
installed do

#use "topfind";;
#thread;;
#require "core";;
open Core.Std;;

Thanks, but the error message stays.

utop # let ratio x y = &n

Float.of_int x /. Float.of_int y

;; &nb
sp; &n

Error: Unbound module Float
